Method and apparatus for processing image content
A method and system are provided for processing image content. The method comprises receiving information about a content image captured at least by one camera. The content includes multi-view representation of an image including both distorted and undistorted areas. The camera parameters and image parameters are then obtained and used to determine to which areas are undistorted and which areas are distorted in said image. This is used to calculate depth map of the image using the determined undistorted and distorted information. A final stereoscopic image is then rendered that uses the distorted and undistorted areas and calculation of depth map.
1. A method comprising:
receiving information about a content image captured by at least one pair of cameras, said content image including a multi-view representation of an image including both distorted and undistorted content;
obtaining, at least one of a camera parameter and an image parameter;
obtaining, using said at least one of the camera parameter and the image parameter, distortion information indicating which content is undistorted and which content is distorted in said multi-view representation;
calculating a depth map of said image using said distortion information; and
rendering a final stereoscopic image that uses said distortion information and said depth map.
2. The method of claim 1 , wherein said at least one of the camera parameter and the image parameter is used to provide a matrix for the at least one pair of cameras.
3. The method of claim 2 , wherein said matrix for the at least one pair of cameras includes distortion parameters.
4. The method of claim 2 , wherein said matrix for at least one pair of cameras is used to determine a warp map.
5. The method of claim 4 , wherein said warp map is further defined as a refinement of a motion vector.
6. The method of claim 5 , wherein said warp map is associated with a prediction mode.
7. The method of claim 1 , wherein said distortion information is provided to obtain a distorted content.
8. The method of claim 1 , wherein said distortion information is provided to obtain an address for a distorted content.
9. The method of claim 1 , wherein said distortion information is used to provide a distortion compensation value to calculate a warp map.
10. A non-transitory processor readable medium having stored therein instructions for causing a processor to perform the method according to claim 1 .
11. A non-transitory storage medium carrying instructions of program code for executing the method of claim 1 .
12. An apparatus comprising one or more processors configured for:
receiving information about a content image captured by at least one pair of cameras, said content image including a multi-view representation of an image including both distorted and undistorted content;
obtaining at least one of a camera parameter and an image parameter;
obtaining, using said at least one of the camera parameter and the image parameter, distortion information indicating which content is undistorted and which content is distorted in said multi-view representation;
calculating a depth map of said image using said distortion information; and
rendering a final stereoscopic image that uses said distortion information and said depth map.
13. The apparatus of claim 12 , wherein said at least one of the camera parameter and the image parameter is used to provide a matrix for the at least one pair of cameras.
14. The apparatus of claim 13 , wherein said matrix for the at least one pair of cameras includes distortion parameters.
15. The apparatus of claim 13 , wherein said matrix for the at least one pair of cameras is used to determine a warp map.
16. The apparatus of claim 15 , wherein said warp map is further defined as a refinement of a motion vector.
17. The apparatus of claim 16 , wherein said warp map is associated with a prediction mode.
18. The apparatus according to claim 12 , wherein said distortion information is provided to obtain a distorted content.
19. The apparatus of claim 12 , wherein said distortion information is provided to obtain an address for a distorted content.
20. The apparatus of claim 12 , wherein said distortion information is used to provide a distortion compensation value to calculate a warp map.
